If `x ,y ,a n dz` are distinct prime numbers, then `x , y , a n dz` may be in A.P. but not in G.P. `x , y , a n dz` may be in G.P. but not in A.P. `x , y , a n dz` can neither be in A.P. nor in G.P. none of these

If x ,y ,a n dz are distinct prime numbers, then (a). x , y , a n dz may be in A.P. but not in G.P. (b) x , y , a n dz may be in G.P. but not in A.P. (c). x , y , a n dz can neither be in A.P. nor in G.P. (d).none of these

If x ,y ,a n dz are distinct prime numbers, then (a). x , y , a n dz may be in A.P. but not in G.P. (b) x , y , a n dz may be in G.P. but not in A.P. (c). x , y , a n dz can neither be in A.P. nor in G.P. (d).none of these

If x,y, and z are distinct prime numbers, then x,y, and z may be in A.P.but not in G.P.x,y, and z may be in G.P.but not in A.P.x,y, and z can neither be in A.P.nor in G.P. none of these

If a, b, c are in A.P., a, x, b are in G.P. and b, y, c are in G.P. the point (x, y) lies on

a, b, x are in A.P., a,b,y are in G.P. and a, b, z are in H.P. then:

If x ,1,a n dz are in A.P. and x ,2,a n dz are in G.P., then prove that x ,a n d4,z are in H.P.

If x ,1,a n dz are in A.P. and x ,2,a n dz are in G.P., then prove that x ,a n d4,z are in H.P.

If x ,1,a n dz are in A.P. and x ,2,a n dz are in G.P., then prove that x ,a n d4,z are in H.P.

If x ,1,a n dz are in A.P. and x ,2,a n dz are in G.P., then prove that x ,a n d4,z are in H.P.

If x,2y,3z are in A.P where the distinct numbers x,y,z are in G.P then the common ratio of G.P is
